An analysis of shock noise components

Abstract

Screech and broadband shock-associated noise linked to the presence of a shockcell structure in supersonic jets are reviewed in this paper. Only underexpanded supersonic circular jets issued from a convergent nozzle are considered here. An overview of the flow and of these two noise components is presented, based on recent experimental and numerical work. Flight effects on broadband shock-associated noise are also introduced, within the framework of aeronautical applications.
